Against white it measures 7.09:1 and against black 2.96:1, so white text is the stronger pairing. That pairing passes WCAG AA for body text. Avoid black text on this color entirely.
One color explored: close hues with real lightness and chroma structure, so the palette is the anchor through value rather than a set of colors.
#f99085 · #d76259 · #aa2222 · #86000b · #4e0003 · #1e0000
The anchor's neighbours on the wheel — everything shares an undertone, so the chord carries color without anything having to be muted to get along.
#ba6919 · #b54911 · #aa2222 · #8f0f38 · #720242 · #540044
The mid-gap pairing — sage and mustard, terracotta and olive. A foil rotated 40–65° toward warm or cool: too far to be kin, too near to argue, carried by temperature and a deliberate value offset.
#d9b170 · #c88c00 · #97743c · #aa2222 · #7f0d11 · #550004
One deliberately opposed voice — a single restrained counterpoint across the wheel, or temperature against temperature where the anchor is too muted to carry a loud opposite.
#00ddf1 · #cf8a82 · #9a726d · #aa2222 · #692824 · #3d1714
The anchor as the only color in the room. True neutrals or complement-warmed near-neutrals let it stay dominant.
#e0f7fa · #c8aba7 · #6c7b7d · #aa2222 · #5a3d3a · #000102
This color as a ground rather than a subject — its own restraint held across a narrow value band, carrying one saturated voice from the opposite temperature.
#e6f5f7 · #bccdd0 · #8ea1a4 · #0f2a2d · #000709 · #aa2222
The opposite hue on the perceptual wheel, tempered to field strength — warm/cool tension without vibration.
#d5faff · #00cadd · #008895 · #aa2222 · #004f58 · #080000
The complement's two neighbours instead of the complement itself — strong contrast with a lower clash risk.
#bcdec5 · #76bfa8 · #6595aa · #aa2222 · #404b6e · #1e0513
Three hues spaced evenly around the wheel; the anchor leads and the other two are held at supporting strength.
#dcfcde · #74ca7d · #496fdc · #aa2222 · #223c92 · #000200
Two complementary pairs offset by 90° — the richest chord, kept usable by a strict lightness hierarchy.

#9C3832 · #8E463F · #7E504B
Its chroma is high enough to carry accents, calls to action, and focal moments; large fields of it will dominate a composition. In palettes it pairs most predictably with its tonal ramp and analogous neighbors; reserve the complementary hue for small, deliberate contrast.
